fpr - convert FORTRAN carriage-control output to printable form
fpr
fpr is a filter that transforms files formatted according to Fortran's carriage control conventions into files formatted according to UNIX line printer conventions.
fpr copies its input onto its output, replacing the carriage control characters with characters that will produce the intended effects when printed using lpr (1) . The first character of each line determines the vertical spacing as follows:
One line
Two lines
To first line of next page
No advance
A blank line is treated as if its first character is a blank. A blank that appears as a carriage control character is deleted. A zero is changed to a newline. A one is changed to a form feed. The effects of a “+” are simulated using backspaces.
In UNIX System V, the asa utility is the standard, not fpr.
Given the following file:
write(*,'(" Blank")')
write(*,'("0Zero ")')
write(*,'("+ Plus ")')
write(*,'("1One ")')
end
Example 1 With actual files:
a.out > MyOutputFile fpr < MyOutputFile | lprExample 2 With only pipes:
a.out | fpr | lpr
Both of the above examples produce two pages of output.

Blank
